In the early 1980's Mr. Asahara opened up a shop selling Chinese medicine. He is said to have made hundreds of thousands of dollars selling potions like tangerine peel in alcohol, and in 1982 he was arrested and fined for selling fake drugs.
Mr. Asahara became interested in yoga, and scholars say he became an excellent yoga practitioner, with very good control over his breathing technique. In 1984 he launched a company called Aum -- the name apparently is based on a Sanskrit word -- that ran a yoga school and sold health drinks.
An expert in marketing, Mr. Asahara traveled to India and Nepal to study Hinduism and Buddhism, and he came back with photos of himself with senior Tibetan lamas, including the Dalai Lama. He used these photos to portray himself as an internationally respected religious authority, and his yoga school became extremely successful.
